Is there any way to directly implement UPI payment in android to a merchant ID/VPA without using a payment gateway like Razorpay / PayU etc?
I have tried using Upi deeplink approach (upi://pay?pa=xxx@xxxx&pn=xxxxxx&mc=null&tid=null&tr=test101&tn=This%20is%20test%20payment&am=10&mam=null&cu=INR&url=null) but it doesn't work
